RAILWAY VEHICLE AND TRACK anarrastn TO CHANGE or'eaen.

To all whom it may come-raj:

lie it known that I, JAMnsHAnrna NEW- row, a citizen of the Commonwealthof Australia, residing at Sydney, New South V ales, in theComn'ionwealth of Australia,

have invented. new and useful Improvements telat ng to Rallway Velnclesand Tracks Adaptable to Change of Gage, of which the following aspecification.

The object of this invention is to provide some cases the superstructureof such vehicles have been made interchangeable with the bodies of othervehicles, and are lifted from the rolllng stock running on one gage ofrails to rolling stock adapted to run on rails set at a different gage.This occasions considerable delay in the transport and delivery of bothmerchandise and live stock. To obviate these difficulties, and to insurethe vehicles running safely on either gage rails, this inventionprovides means whereby the wheel axles, which are formed in two. equallengths, are caused, while running, either to lengthen or shortenautomatically at the station where the two gages are joined by a doubleset oi. tapering lines.

. Referring to the accompanying drawings,

:in which similar letters are used throughout the diiierent views toindicate similar parts: Figln-e 1 is an elevation ofan extendlble axleand wheels set tonarrow gage lines,

with horseshoe strap and block piece in elevated position, centralsupporting hearing, and, thesuspending frame, all shown in longitudinalsectional elevation. Fig. 2 is anelevation and section of the parts inFig. 1., but extended to the wider gage lines, with strap and blockpiece lowered into position between the ends of the half axles. Fig. 3is a central longitudinal sectional elevation of a half axle, enlarged,showing the cir ail ar and roller bearing and oil feeding chan-Specification of Letters Patent.

Fig.1.3 is a half lan oi Fig.

This invention confined prlncipally to the reconstruction of the axleparts of var ous kinds of: railway vehicles, but exeluding locomotives.w Q

he type of axle illustrated is especially serviceable for railwayvehicles having overhan in axle boxes. In such the framework 23 i2! 0than the over-all wid th ot the ore an extenchble axle may be ing, whilethe inner journal A, formed be tween the collars A" nd A'flhas itsspecial bearing G to lsu sport it, two of whichare provided in the halongitudii'ially and securedby tlie bolts D to the undercarriageattaclnnent F. The

collars A, whichin Fig. 1 are shownin 110' their close position, areprovided with nger D, which is divided wheel axles and central.bearings, andshow- The outer journal A would Lrunin the usual.overhanglng axle box bearice bearings A held in position by the screwthreaded ring A, side Fig. 7. The circular track in this figure is shownof larger diameter than in Fig. 8, for the purpose of insuring that theballs in each case will take their hearing on the contiguous aXle endwithout coming into contact. The means for lubricating these bearings isby the central oil channel A which is also in communication with the oilfeeding channelA for lubricating the journal A The journalsarenecessarily longer than their bearings to provide for the lengthwisemovement, which is equal to the difference be tween the two gages onwhich the wheels are required to run. The fixed collar 13 is provided asan additional means for securing the wheels a screw threaded bolt Bserving the attachment. The chambered par-ch? serves as an oilreceptacle for lubrieating both the bearings C, the inner collars A, andthe ball bearings A The distance block F, which is essentially of awidth equivalent to the difference between the two, gages, is likewiselubricated by means pf the revo-lving collars A as they run in the oilbath. These collars take their bearing against each other when the blockFis raised above them, as in Fig. 1, but in its lowered position, as inFig. 2, it serves as a thrust block separating the two inner collars,and having the ball bearings A in Contact with the sides. This occurswhen thewheels B are at their widest gage. The upper guide fian'ges D ofhanger D, being held in position between the side parts of the undercarriage attachment E, serve the purpose of a chamber G (Fig. 2) for theblock F to slide in, it being secured to the horseshoe strap H by thebolts H The said strap is retained within guides formed by theprojecting pieces I (Figs. 4, 5, and 6). The st raps and block piecemove together when the former is brought into contact with thecollapsible gradient track 1 which comprises the gradient part J and thelevel part J the former being serviceable for producing the liftingmovement to the strap H, while the level part is used to maintain it inthe elevated position until one pair of wheels have PHSSQCl fIODI thebroad to the narrow gage, the level part bemade essentially of a lengthequal to the distance to betraversed by the wheels from one gage tothjeother. It is necessary that theblock piece F be lifted quite clear ofthe "collars A before the axle A commences the shortening movement,which is brought about by confining the flanges of the wheels betweenthe rails K and K which converge fron the broad to thenarrow set ofrails. The 'removalof the block F insures this taking place, and whenthe narrow gage is reached the saidblock takes its position on the topof the collars A": When the strap H is free from the track J it will beseen that the block F will remain supported upon the collars, as in Fig.1, until the movement of the vehicle is reversed by passing it from thenarrow to the broad gage; when the lengthening of the axle takes place,and the block F, by its own gravity, descends into the positionindicated in Fig. 2.

To permit of the gradient track being laid in the prone position, as inFig. 11, the sloping part J is pivoted to the level part J by the pin Jthe said'level part being, in turn, secured by means of pin connectedlinks J? also attached to the fixed chairs J upon thesleepers L. Thepart J is supported centrally by the pin connected link J attached atits lower end to the slide block J 6 running upon the incline M formedat the inner end of the bed plate M To the link J is attached theconnecting rod N secured at its other end by the pin J to the slideblock 0, which is also connected to the jointed lever secured at itsouter end by the pin P to the slide block The cen ter pin P connects thejointed lever with the cranked lever Q attached to theoperatiiig spindleQ supported in the bearings R. This crankedlever is causedto pass fromits forward to its backward position by means of the operating lever Shaving a 1 weight S to retain it in p dsition. i

Fig. 11 shows the device in its prone position', with the slide block J6 moved down the sloping part M, and the slide blocks .0 andO movedalong the level part M of the bed plate M The parts J and J are thus putout of action, and prei' entedfrom being an obstruction to trafiic. i

Having now described my invention, what I consider novel and desire tosecure by Letters Patent is:- i
